Hippie-inspired beach waves continue to dominate the red carpet, but at the 52nd Annual Grammy Awards, stylist Robert Vetica took curls a decade further. "It was '70s-inspired, like Bianca Jagger goes to Studio 54," says the coiffeur about the hairdo Jennifer Lopez, his muse of the evening, wore. "I'm kind of over messy beach hair—I wanted to make a stronger statement by giving her hair style and shape. It had lots of curl and massive volume, with more width than height."

In eschewing carefree 60s layers for Guy Bourdin worthy curls, Vetica trimmed Lopez's damp hair to one length ("When you blunt the hair it makes curls appear stacked and gives volume at the ends"). Next, he blew strands dry with a round brush to maintain hair's buoyancy and fashioned a middle part. Misting a mild fixing spray, he then created spirals with a one-inch curling iron. Working from the back to the front on each side, he finger-brushed the set with Moroccanoil Hydrating Styling Cream ("It holds the wave and takes out any dryness from the curling iron"). For a va-va-voom finish, Vetica smoothed waves with a bristled brush and backcombed under each section using a wide-tooth comb. A healthy dousing of Morocconoil Luminous Hairspray (available next month) and Lopez's head-turning do was complete.
